Direct proof of use
TRT Haber reported on February 12, 2018, that domestically produced MPT-76 rifles were among the important weapons used by Turkish troops assigned to Operation Olive Branch in Afrin. The same report said the rifles were produced at MKE's Kirikkale weapons factory and described a shipment of 4,500 additional MPT-76 rifles for delivery to the Land Forces Command.
The direct conflict-use claim is therefore limited to Turkish fielding of the MPT-76 during the Afrin operation. The available source does not identify individual firefights, units below the Turkish troop level, or quantities already carried inside Afrin.

Timeline
Turkey launched Operation Olive Branch on January 20, 2018, against the Afrin area in northwestern Syria. CSIS described the operation as a Turkish military action beyond the southern border directed at the Syrian Kurdish canton of Afrin, with Free Syrian Army elements and active Turkish military support.
By March 15, 2018, Anadolu Agency reported that Turkish troops and Free Syrian Army forces had reached Afrin city's border after clearing villages and strategic terrain during Operation Olive Branch. This operational context frames the period in which TRT Haber placed MPT-76 rifles with Turkish troops in the Afrin campaign.

Narrative
In this conflict entry, the MPT-76 appears as a Turkish infantry rifle rather than as a stand-alone platform with independently documented effects. TRT Haber's report connects the rifle to Turkish personnel in Operation Olive Branch, while broader operation reporting places those personnel in the Afrin offensive against YPG/PKK-linked forces as described by Turkish and independent policy sources.
The evidence also separates use from production and transfer. The same TRT Haber article linked the rifle to MKE production, described technical characteristics, and reported additional shipments to the Turkish Land Forces Command, but those production and shipment details are supporting context rather than separate proof of battlefield use.
